Acrel AC Single Phase Ammeter Display LED With RS485 Communication AMC48-AI/C Panel Mounted
AMC Series programmable intelligent single phase meters, adopting AC sampling technology, can measure current of single-phase grid indirectly. It can be used for local display, and connecting industrial control device to form measurement and control system.
Using AC sampling technology, it can directly or indirectly measure the power, power, voltage, current and frequency of a single-phase or three-phase power grid. It can be used for local display, and can be connected with industrial control equipment to form a measurement and control system.
The instrument can have RS-485 communication interface and adopt Modbus-RTU protocol, with analog output, relay alarm output and switch input/output.
